Your first impression of a book cover, a class or a city is usually the least informed opinion you’ll ever have about it.

First impressions arrive fast and feel certain, which is an unfortunate combination. At that moment you hold the least information about the thing that you will ever hold, and the judgement is running mostly on surface and mood. It is the opinion most likely to be wrong and, because it came first, the one most likely to stick.

Give something you wrote off a second honest look this week: a class, a book, a person you decided about in a minute. Three more encounters is a fair test, and you can keep the verdict if it survives.
